Enum EventKind 

pub enum EventKind {
    User,
    Assistant,
    ToolCall,
    ToolResult,
    System,
    Compaction,
    SubAgentSpawn,
    Attachment,
}

What one normalized event represents.

Note: some agents (Claude Code) attach tool calls to Assistant events rather than emitting standalone ToolCall events; the variant exists for agents that log them separately.

Variants

User

Assistant

ToolCall

ToolResult

System

Compaction

SubAgentSpawn

Attachment

Non-message context injected into the window: deferred-tool listings, skill listings, MCP-server instruction blocks, IDE/file context, reminders (Claude Code attachment lines). Carries no token usage; used by context-bloat attribution (analysis::context).

Trait Implementations

impl Clone for EventKind

fn clone(&self) -> EventKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for EventKind

impl Debug for EventKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EventKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for EventKind

impl PartialEq for EventKind

fn eq(&self, other: &EventKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for EventKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
